Not an analyze on a very big number of patients (nine):

> Nine patients with late-stage prostate cancer performed 34 minutes of high intensity exercise on a stationary cycle, with blood serum collected immediately before and after, and then again 30 minutes post-workout.

>The team found the serum obtained immediately after this “dose” of exercise contained elevated levels of anti-cancer myokines resulting in suppressed growth of prostate cancer cells in vitro by around 17 per cent.

>Serum myokine levels and cancer suppression returned to baseline after 30 minutes

So if exercise can kill cancer cells, it is probably really bad for healthy cells. I don't want to risk it.

Here is tl;dr:

“The optimal dose of exercise is not yet known, but it is likely to be 20-plus minutes each day and must include resistance training to grow the muscles, increase the size and capacity of the internal pharmacy, and stimulate the myokine production,” he said.

“This study provides strong evidence for the recommendation patients with prostate cancer, and likely anybody with any cancer type, should perform exercise most days, if not every day, to maintain a chemical environment within their body which is suppressive of cancer cell proliferation.”

From the article.

That doesn't seem very useful, as a layman.

EDIT: we're not talking about the benefits of exercise in general. That's well established and I am in no way questioning that. We're talking about myokines and cancer suppression.

Conversely, doesn’t exercise activate mTOR-mediated signalling?

Being active for half your life protects you from cancer for the rest of it, by that logic. Fitting that to a normal schedule, it makes sense. And points to sedentary life as a cancer permissive style.

So I'm totally talking out of my ass here but there's a variety of things that its important to have happen regularly in your body but not constantly. So even these short doses may have a high net benefit

Interesting, I’m currently dealing with a metastatic recurrence and I’m a very active individual, was training 6x a week in martials arts at the time of my recurrence in April- but had stopped weight lifting the last year to accommodate the extra classes.

I have a very rare and unusual cancer so I’m always following research to integrate and adapt my daily habits to extend my time between recurrences. Im on immunotherapy right now but having some disease progression, im going to add weight lifting back to my routine and see if there’s any changes between my scans

Learning about reishi and turkey tail from this sub years ago was a game changer for my chemo side effects

When can we get this in pill form? Exercise just isn’t an option.

I'm a rehab doc. Exercise has SO MANY research-supported benefits to the body and mind, that if I were to say the same thing about any other treatment modality, people would be convinced I'm selling snake oil. It is genuinely astounding how good it is for us. If only everyone 1) wanted to do it, and 2) had a lifestyle that allowed them to exercise regularly in a safe and enjoyable environment.

My husband, who worked in nursing homes for a while, says, "Never stop moving. When you stop, you die."

Physical therapy sucks, but it's very much a if you don't use it, you lose it, situation.

Yeah I’m 30. And hopefully I’ll be going strong for a long time.

I work manual labour (relatively lightweight manual labour, but still manual labour) and I spend my weekends hiking and climbing.

I eat well, and I drink in moderation. I’m hoping that baring major injury I’ll be able to keep doing the things I love for a long time.

How elevated were levels?

Exercising once probably doesn’t help a ton, but if you exercise twice a day or more for decades, it seems like it could be a massive benefit.

And the elevated levels might be prolonged in those who exercise regularly, just like a lot of things are improved only slightly by one bout of exercise but vastly improved by years of regular exercise

I am totally not dismissing the value of exercise but when my father had a high PSA he was advised to stop riding his bicycle for three weeks because it could give false high readings.

That is specifically due to the pressure on the prostate from the bicycle seat though I think. No one will tell you to stop riding a bike for any other cancer generally that I am aware of. Plus assuming keeping all treatment, avenues open, surgical processes and seed, therapy or brachy therapy would be going through some sensitive bits, i.e. the taint. So you don’t want it to be sore already before that I would think.

True, I still have a good few years in them yet.

Hopefully they keep going though, I know plenty of people in their 50s who live like I do and they're only getting stronger with time.

I feel that's 100% true. Whenever I eat junk food, I'm like, I will go to the gym to burn it off, but then my body feels like it doesn't wa t to exercise later. Similarly, when I exercise, my body wants more healthy food.

So it's the same thing as always:

Exercise is crucial in today's world. It's so easy and so tempting to constantly be sitting and consuming via our screens and since the vast majority of us are no longer doing any sort of manual labor, a dedicated exercise routine is crucial.

Exercise is known to have benefits in multiple arenas. Even if you don't have a concern for cancer, the benefits to mood and sleep alone should be a great motivator.

I dunno, there's significant ground between regular running and struggling to walk. You'd think if the running wasn't helping (or an index of something else that helps, like general health motivation) then he'd know plenty of people who don't run but haven't lost much ability.

Exercise (especially cardio) is so effective for mood and appetite regulation for me that I'm experimenting with running 6-7 days a week just to get "booted up" correctly at the beginning of the day. I've always had scheduled rest days before, but they were always just less nice, and 3 km at easy pace really isn't a lot of stress on the body.

Man I hate this kind of thing. What's he supposed to do, be less active because one day his knees may suddenly go bad? Your knees will eventually go bad regardless. Moderate daily activity is the best way to prevent it.

There’s a lot of data that supports it. I’m also a nurse with a master’s degree (so, extra research training!) and have seen it in the numbers and it’s glaringly obvious in real life. Anecdotally the people who are sedentary may not be dying but they are miserable af.

I’m sorry to hear about this but so glad to hear you’re staying active! Weight training has endless benefits across the board and really supports other sports too.
